What do HCF and LCM stand for?
HCF means the highest common factor of two or more numbers. LCM means the lowest common multiple of two or more numbers.
Why you need LCM and HCF in maths?
It's kind of an inverse relationship. The product of the GCF and LCM of two numbers is the same as the product of the original two numbers, so as the GCF increases, the LCM decreases and vice versa. LCM is divisable by HCF.
What is the HCF and the LCM of 175?
You need at least two numbers to find either of those.
What is the hcf of 41 and 90?
9
What is h.c.f and l.c.m?
They are: h.c.f or HCF means the highest common factor of two or more whole numbers and l.c.m or LCM means the lowest common multiple of two or more whole numbers
Can the HCF of two numbers be a factor of their LCM?
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.
Can HCF and LCM of two numbers be 27 and 288?
No. The LCM MUST be a multiple of the HCF.
The LCM of two numbers is twice their HCF?
5 and 10 lcm- 10 and hcf= 5
Can two numbers have 16 as their HCF and 380 as their LCM?
LCM = product/HCF so product = LCM/HCF in this case 380/16 which is 23.75, so the answer to your question is no.
The product of two number is 20736 and their HCF is 54 find the LCM?
LCM = Product/HCF = 384
How do you find sets of two numbers if HCF and LCM are known?
You cannot. The numbers 2 and 12 have hcf = 2 and LCM = 12 The numbers 4 and 6 also have hcf = 2 and LCM = 12 So if you just knew the hcf and LCM you would not know which of the two was the required pair.
If the HCF and LCM of two numbers are 17 and 102 respectively and the HCF and LCM of two other numbers are 68 and 476 respectively then find the sum of the HCF and LCM of these four numbers?
HCF of 17 and 68 is 17 ..( Lowest Prime factor ) LCM Of 102 and 476 is 7*2^2*3*17 which is 1428 .. ==> Sum of HCF and LCM are 1428+17= 1445 .
What numbers have a HCF of 3 and a LCM of 3?
Two or more numbers are needed to solve for HCF or LCM.
Does the HCF of any two no is always a factor of their LCM?
If two numbers are expressed as ab and cb this is easier to work out. Assume that a and c have no common prime factors. Thus, the HCF of the two numbers will be b. The LCM is the two numbers multiplied by each other, divided by the HCF. So the LCM will be abc. b is a factor of abc, and so the HCF will always be a factor of their LCM.
How would you explain the LCM of the two numbers is their product?
The LCM of two numbers is their product if and only if the two numbers are co prime, that is their HCF is 1. Otherwise their LCM in not their product, in fact, it is their product divided by their HCF.
What is the relation between HCF and LCM?
Since the product of two numbers is equal to the product of their GCF and LCM, the GCF of two numbers is equal to their product divided by their LCM and their LCM is equal to their product divided by their GCF.
What do HCF and LCM stand for?
HCF means the highest common factor of two or more numbers. LCM means the lowest common multiple of two or more numbers.
